How to set $_FILE without html browse button ?

Question

I have a form that contains an html file browse button ( <input type=file /> ). User select a file by clicking browse button and submit the form. On form submission new php script (submitToServer.php) is called that use that file to upload it to the server.

Now I want to upload that file without using browse button because file name and path is always same when we upload. How can I do this?

currently submitToServer.php file handle file using browse button like this:

$errorCode = $_FILES['claimsfile']['error'];
$claimsFileLocation = $_FILES["claimsfile"]["tmp_name"];
$claimsFileName = $_FILES["claimsfile"]["name"];
$claimsFilePointer = fopen($_FILES["claimsfile"]["tmp_name"], "r");

Answer 1

I suspect that's not possible due to security reasons, you do have to click the browse button and specify a file first. Pre-filling this field with some tricky paths (../../etc) and not pressing the browse button would have created security problems (if you could imagine for a while)

Answer 2

You can't. HTML does not allow it for security reasons.

The only way to control which file is uploaded from serverside would be to use an applet (java, activeX, flash) - and even then you'll need to use signed code to get out of the sandbox.
